>>902375>>902380oh, right, the question was how to do this without a calculator. well, use scientific notation to add/remove zeros to the left or the right. from there, you can do the basic operations in paper or something (in the previous case, you could, say, "transform" 0.03 into 3000000*(10^-8), and then divide that by 362488.
but in any case, that's kind of stupid, since there is no need to do that.
